The Zestimate's® accuracy depends on location and the availability of data in an area. Some areas have more detailed home information available — such as square footage and number of bedrooms or bathrooms — and other areas do not. The more data available, the more accurate the Zestimate® value will be.
To improve Zestimate® accuracy, we allow homeowners to edit their home facts and then we incorporate this information into our Zestimate® calculations. For steps on how to edit your home facts, click here.
Be aware that in some areas, we might not be able to produce a Zestimate® at all, but we do have some basic information on the homes. You can also view the Zestimate Accuracy Chart for more information.
